The Tungsten Carbide Hand Set is one of our heaviest tools. Thick Shanks, and heavy duty heads reinforce the Tungsten Carbide Tip, to provide a stable base for the tip, and also provide the user with a good grip for such a heavyweight tool. The Tip Grade is ideally suited to the material you are working with, Stone tools being harder, granite tools being tougher. We’ve had many years of customer feedback to perfect the correct grades of carbide for each tool.
